The Westlake University team has developed a new optical fiber spring sensor with a detection limit of picobarn, which may be used to discover microscopic physical phenomena.
Spring scale is a macroscopic force meter, which is often used to weigh various fruits, vegetables, and commodities. If the size is reduced to the micro-nano scale, is it possible to calibrate and "weigh" tiny forces like a spring scale?This requires a significant reduction in the detection limit of the sensor, placing extremely high demands on the precision of the device. In previous studies, ...MORE
Perceiving the microscopic world with "light"丨Qiu Min's team at Westlake University has made progress in the field of optical fiber micro-force sensing
How much light pressure is there in the playful trail of a comet?How much turbulence is responsible for the roaring sonic boom when the plane takes off?Interesting physical phenomena caused by complex stress fields - comet trail and complex airflow (source: sina)Force is an important reference quantity in explaining physical phenomena.Let's open our eyes wide and enter the microscopic wor...MORE
Qiu Min's team at Westlake University: The influence of film thickness of amorphous Si thin film on laser-induced periodic structure
Research backgroundIn 1947, scientists at Bell Labs invented the world's first transistor, which triggered a revolution in microelectronics technology and profoundly changed the way of life around the world. As electronic devices become increasingly miniaturized, finding a simple, fast, and low-cost method of manufacturing micro-nano components has become a huge challenge. Although traditional ...MORE
Development of fiber-optic endface-integrated superstructured surface electro-optic modulators by Min Qiu's team at School of Engineering, Westlake University.
Electro-optical modulator is one of the core devices in the field of optical communication. By applying an external electrical signal, the amplitude, phase, polarization and even frequency of the light wave are changed, so as to load the external modulation signal onto the light wave and realize the conversion of electro-optical signals. Traditional on-chip integrated electro-optical modulators...MORE
Work of Qiu Min's Lab Recently Published in NC：Full-color Inkless Printing with Femtosecond Laser
Diameter of 2 inches, feel light as cicade wings; pattern contains 13 colors, without using a drop of ink, full of color and will also last shining ...... Last summer, when each of the first undergraduate students of Westlake University opened their acceptance letter gift boxes, all of them were surprised to notice this chic "science meet and greet" wafer picture inlaid on the admission plaque....MORE
